reddish, which clouding often extends to the hind margin. 

 Cilia as above. 



The principal variation found in this species is in the 

 number and size of the yellowish spots, of which that in the 

 middle of the discal cell, two in the first transverse row, and 

 four in the second, are the most constant, the rest becoming 

 in many cases, in the male especially, indistinct or cloudy ; 

 on the other hand a cloudy indication of an additional spot 

 near the base is often visible. In the hind wings the first 

 round sub-marginal spot is often reduced to a mere dot, and 

 sometimes obliterated, although the yellowish blotch in which 

 it lies is not reduced in size. There is also variation in colour 

 which is local or climatal, specimens from the New Forest 

 and other parts of the south of England occasionally ex- 

 hibiting a more fulvous colour in certain of the yellowish 

 spots, and thus indicating a tendency towards the ordinary 

 South European form, which has all these spots reddish- 

 yellow, and is held to be the type of the species ; our paler 

 spotted specimens being included in what is known as the 

 variety jEijcridcs. A variation in quite a contrary direction 

 takes place in the north of Ireland, where the dark brown 

 ground colour is more blackish and the pale spots are often 

 nearly white. All possible intermediate gradations occur ; in 

 South Wales the males are darker and more velvety than 

 ordinary English specimens, while the females are often very 

 strongly marked, and their spots yellower ; and in Devon, on 

 the slopes of Dartmoor, Major Still finds a variation of the 

 male which has the pale spots of the fore wings rich yellow, 

 but reduced to four in number, and those of the hind wings 

 to two, the remaining usual spots being faintly indicated as 

 paler clouds in the rich dark colour of the wings. The 

 ocellated spots, however, are as usual. A specimen is re- 

 corded, almost of an orange colour, taken at Dinedor Wood, 

 Herefordshire, in 1884, and a male of a tawny colour has 

 been obtained in the New Forest; Mr. S. Stevens has one 

 with the usually dark markings of a pale golden brown, and
